A bad office would be an office with no external views and without a wall to put books, images or magazine tear sheets on. Some sort of display - I'm a very visual person. I spend too many hours in here every day, but I do like my office because I'm surrounded by things that inspire me - and I can see the team. I've avoided the anonymity of a lot of offices; the point is that this is a personalised space, a good framework for my thinking. I dispensed with standard office furniture and bought my own - I got rid of the provided desk pronto. I just think there's something wrong about editing a well-known style magazine and people coming in and finding me sat behind a hideous desk.

I am very organised, but there's a lot to organise. That's why my diary is super important to me - it's got sections: to do, to phone, tasks to delegate, personal stuff. One thing I do live by is 'Do the hardest thing first' and then you can sort of 'treat' yourself by knocking off a few easy things. I only ever write in my diary with my Mont Blanc platinum fountain pen - I think that the things you use every day need to be things you really love. That pen goes with me everywhere. Touch wood, I tend not to lose my possessions as I really value them.

I am a private person, but in my professional life I like to surround myself with personal things. All the books belong to me - they're references for work. At home it's all my novels on the wall. My high- heeled shoes are very important to me; I'm legendary for doing long days at furniture fairs in heels. I wear flats to get to work, though.

People are surprised by the cartoon characters on the shelf because I don't seem like that sort of person, but I love Mr Happy - he makes me, er, happy! Bright yellow is my favourite colour, and I call it Mr Happy Yellow and use it on the pages of the magazine. There's something positive about it that reflects my optimism. I'm very much an optimist. A realist as well, yes. But a realistic optimist.
